Comparative StudyHigh body mass index and long duration of intubation increase post-extubation stridor in patients with mechanical ventilation.
Approximately 20% of mechanically ventilated patients experience post-extubation stridor (PES) and reintubation, which subsequently may lead to an increased risk of morbidity and mortality. The risk of PES development is significantly higher in obese patients. Low air leakage between the endotracheal tube and the trachea, following cuff deflation, may indicate a higher risk for the development of PES. ⋯ The mean BMI was 36 +/- 13 kg/m2 in PES patients and 24 +/- 7 kg/m2 in non-PES patients (p = 0.046). BMI > 26.5 kg/m2 (OR: 1.2), low cuff-leak volume (< 283 ml) and mechanical ventilation required for more than 5 days (OR: 0.9) were independent variables for PES occurrence. We therefore suggest that non-obese patients, short-term intubated patients and those having a high air leakage around the endotracheal tube could be extubated without much difficulty.

Comparative StudyUsefulness of warm fluid in acute burn resuscitation: an experimental study in dogs.
Hypothermia is a common complication in patients with extensive burns, receiving massive volumes of fluid for resuscitation at ambient temperature. It is therefore important to maintain the body temperature of patients with extensive burns. The present study was performed to evaluate the usefulness of warm fluid for burn injury resuscitation. ⋯ The urinary output was better in animals treated with warm fluid, indicating the improved hemodynamic state in these animals. These results suggested that the hemodynamic state in acute burn shock was ameliorated by the use of warm fluid. Therefore, warmed fluid resuscitation might be useful to perform immediate excision and grafting for the patients with extensive burns in acute burn shock.
